I Application led June 1,

' This invention relates to turbine irrigation l pumps, and is an improvement on myinvenis mounted at the surface of the ground toA which the' discharge-pipeyis attached. Extending fromthe pump-head to thepumpsection is a pump-shaft, by means of Whlch i the pump-section is operated, and surrounding the pump-shaft is an oil-tube which re'- 'tains lubrication for pump-shaft bearingsI which are supported by the oil-tube. It is common practice to attachthe lower end of the oil-tube to the upper partI of the pumpsection and to place a tension on it by means lof a nut located at the upper end thereof and in the pump-head. It is highly desirable forvarious reasons to maintain a sub- `stantial tension on the oil-tube. One reason is to keep the oil-tube absolutely concentric so that the bearings will support the pumpshaft in exact axial alignment so that there will be no whipping of the shaft. The present manner of applying tension to the oil- A tube is not entirely satisfactory. A considerable degree of tension is applied to the upper end of the .oil-tube, but .by reason of the.

i shaft to whip.

Weight thereof the oil-tube has less tension at the lower end. One big objection to and deficiency of this method of applying ten' sion is that the initial tension very often diminishes, because of the great distance and many joints between the upper and lower ends, so that it is possible for the oil-tube to move out of concentricity and for the pump It is one of the important objects of this invention to provide a pump of the character mentioned in which tension is applied to the oil-tube at intervals between the upper' and lower ends.

Another object of the invention is to provide a novel form of tensioning-joint, per se.

Other objects and advantages of the invention will be made evident hereinafter.

In the following description I illustrate the invention applied to a particular design of irrigation turbine pump. My invention,

however', may be used in'various types of pumps and I, therefore, do not wish to' have my invention limited to the type' of pump shown but wish it to be construed in the Referring .to the drawing in which I illustrate my invention: F1g. 1 is a vertical-view, lpartially sectioned, 'of a pump embodying the features of -thls invention. l L

Fig. 2 is an enlarged vertical section of a tensioning-joint of the invention.

,f IF1g.g3-is a section taken onthe line 3 3 of 2. l Referring in detail to Fig. 1 of the drawing, a well casingl is extended into a well.

.Mounted lon afoundation 12 atthe upper end of a well is a pump-head 13 and extended downwardtfrom the pump-head 13 into the well is a column-pipe or discharge-pipe 14. Secured to lthe lower end of the ,dis-

charge-pipe 14 is a pump-unit 15, this pump- Y the lower end of the well below the water-level thereof. The

pump-section 15 has impellers 17 which are` mounted on a pump-shaft 18.' The pum shaft 18 extends upward through the discharge-prpe 14 and is` drivably connected w1th a pump-head 13.

Surrounding the pump-shaft 18 is an oiltube20 which carriers bearings 21 in which the pump-shaft 18 is joul'naled. A 'Iheflower lrend of the oil-tube is secured at 23 to the :upper part of the :end of the oil-tube 20is threadedly secured pump-unit 15. lThe upper to a packing member 27 which is supported by a'discharge casting 28 of the pumphead 13.

The oil-tube 20 isjsupported at intervals between the upper and vlower ends thereof motor 19 which forms a part ofthe by tensioning-means or tensioning-joints best illustrated in Figs. 2 and 3. 'The discharge-pipe 14 is made up of lengths of pipe 30 whlch are threaded at the endsv thereof and which are securedtogether by couplings 31. Adjacent ends 32 of the lengths of pipe 30 engage opposite faces of a ring 33 which forms a part Aof a tensioning-spider 34. The spider 34 is rigidly secured in place by the engagement 'of the end faces 32'of the pipe 30 with the side faces of the ring 33.. Extended radially inward from the ring 33 is a plurality of webs 35. -Formed integral with thewebs 35 at the inner ends thereof is a hulp36 which is provided with a smooth i -'cylindrical bore 37. rlhe oil-tube 20 is composed of lengths of tubing 39 which are threaded at'the ends thereof. The threaded ends of the" tubing 39 are screwed into a` nut-coupling 40 which is disposed directly above the hub 36. vjTli'e upper part of the hub 36 is provided with an annular countersunk seat 41 which is engaged by the end of a cylindrical projection 42 formed on the lower end of the nut-coupling 40. The nutcoupling 40 is screwed downward on the upper end yof the lower length of tubing 39 to such an extent that it is resting on the hub 33 and is pulling upward on the lower length of tubing 39 so that a tension is placed on this tubing 39. A bearing 21 is placed at ,each tensioning-joint. Each bear, ing 21 extends intothe upper end of one of the lengths of tubing 39. The upper end of' 2 the lower pipe 30 length of tubing 3 9 are Iirst assembled. rlhe next operation 1s in the drawing,

to install the tensioning-spider 341 'inis is done by placing the spider at the upper end of the lower length of pipe 30, so that the ring 33 rests thereon and so that the hub 36 surrounds the upper end ot the lower length of tubing 39. lhe upper threaded end of the lower length of tubing 39 extends above the collar 36. rlhe inner part which is assembled isthe nut-coupln 40. rThe nutcoupling 40 is screwed onto t ie upper threaded end of the lower length of tubing 39 until the cylindrical projection 42 thereof engages the annular seat 4l. After this engagement has been made it will be seen that the nutcoupling 40 cannot move down any more, and that if the nut-coupling is rotated the upper end of the lower length of tubing 39 must move upward., rllhe nut-cou ling is then turned, and the upper end ot t e lower length of tubing 39 is moved upward. ln view of the fact that the lower end of this tubing 39 is secured, a tension will be placed on it. 'lhe next step is toinstall the bearing 21. After the bearing 21 is placed, as shown the upper length of tubing 39 in Fig.. 2 1s screwed into the upper part ot the nut-coupling 40 so that the lower end 46 thereof engages the cylindrical projection 45 of the bearing 20. The upper length of pipe 30 in Fig. 2 is then screwed into the coupling 31 so that the lower end 32 therelengths ot tubing 39. rlhe ends 46 ot neef/'gees' ot engages the ring 33 of the tensioningspider 34, thiis Aclamping it tightly in place. 'lhe other tensioning-joints of the column pipe are assembled in the same manner as the one shown in Figs. 2 and 3.

F rom the foregoing description it will be seen that the oil-tube 2O \will have a uniform tension applied thereto throughout its entire length.

sion. will be permanent because there are no interposed joints which will give and diminish the original tension of the oiltubel Ordinarily the length ot' the pipe 30 is about twenty feet; therefore, tension is applied to the oil-tube at every twenty feet. lt will be seen that the oil-tube will be. absolutely concentric, and the bearings 21 will maintain the pump-shaft 18 in accurate axial alignment so that there can be no whipping and no attendant stresses which would bring about a premature breakage of the pump-shaft. j

An important part of the invention is its simplicity of construction; rEhe spider 34 serves vthe purpose of centralizing'the oiltube and also serves as a support for the nutln view `-ot' the actthat the' tension is applled at every joint, thi-stencoupling 40 which also serves a dual purpose. rlhe nut-coupling 40- acts as a coupling for the lengths ot tubing 39 and also as a means for applying ytension to them.
